Fix: Outlook Signature Not Showing Images

Setting up a proper email signature is a must, irrespective of the email client you’re using. Companies have specific guidelines that employees must follow when creating their email signatures. Oftentimes, the company logo is also added to the signature. But Outlook may sometimes fail to show your email signature image(s), especially when you reply to emails. Instead of showing the image, the email client often displays a small rectangle. Let’s see how you can get this sorted out.

How to Fix Outlook Signature Not Showing Images

Compose Emails in the HMTL Format

Outlook may fail to display your signature images properly if you’re using the Plain Text Format. Use the HTML format instead and check the results.

Navigate to File and select Options.
Then go to Mail, and go to Compose messages.
Select the HTML format and save the changes.

Update Outlook

If this issue is caused by a known bug, chances are that Microsoft already fixed it in the latest Office release. Install the latest updates and check if the issue is gone. Go to File → Office Account → Update Options → Update Now.

Launch Outlook in Safe Mode

If the issue persists, launch Outlook in Safe Mode. If this problem is caused by a faulty or incompatible add-in or extension, it should not occur in Safe Mode.

Press the Windows and R keys and open a new Run window.
Type Outlook.exe /safe in the Run window and press Enter.
When prompted, confirm that you want to launch the app in Safe Mode.
Compose a new email and check if the signature image is visible now.

Create a New Email Signature

Alternatively, you can delete your current signature and replace it with a new one. Take a screenshot of the problematic image and save it using a different format. Then add the new image to your new signature, save the settings and check the results.

Go to Settings, select Show all Outlook settings.
Then select Mail and go to Compose and reply.
Create your new signature.

Repair Office

If your image problems are caused by corrupted Office files, repairing your Office Suite should fix them.

Go to Control Panel, and select Programs.
Go to Programs and Features and select Office.
Then hit the Change button.
Run the Quick Repair tool.
If the problem persists, launch the Online Repair tool as well.

Create a New Outlook Profile

If your Outlook profile got corrupted, you may experience all sorts of glitches, including the signature image problem we’re covering in this guide.

Launch Outlook, go to File, and select Account Settings.
Then go to Manage Profiles and select Show Profiles.
Add the new profile but don’t delete the old one.
Check if the image issue affects the new profile.

Maybe Your Recipient’s Email Client Is to Blame

Not all the email clients out there automatically download media files, and this includes your email signature images. This is a handy security measure meant to prevent hackers from using media files to inject malware into your computer.

In this case, there’s really nothing you can do about it. Your recipient needs to specifically instruct their email client to download the images attached to your emails.

Conclusion

If Outlook won’t show your signature image, make sure you’re composing your emails using the HTML format. Create a new signature using a new image and check the results. Additionally, run Outlook in Safe Mode, repair Office and create a new Outlook profile.
